Christology and Salvation
Christology and Salvation
This domain tests the Church's confessions about Jesus Christ and the meaning of salvation: the hypostatic union, the two natures and one Person, Marian titles, Christ's human will and knowledge, and the major atonement models. Answers need Chalcedonian precision, not devotional vagueness.
Core rules
- Chalcedon (451) defines one divine Person in two natures, divine and human, without confusion, change, division or separation. Each nature keeps its own properties.
- Ephesus (431) calls Mary Theotokos because the Person she bears is the divine Son; it does not mean divinity originates from her.
- The communicatio idiomatum lets predicates of either nature be attributed to the one Person: the Lord of glory was crucified (1 Cor 2:8).
- Constantinople III (680-681) condemns monothelitism: Christ has a human will fully conformed to the divine will. His human knowledge is real, though some things are known through his divinity.
- Salvation is accomplished by the incarnate Son's life, death, resurrection and ascension. Catholic theology emphasizes sacrificial, vicarious satisfaction and merit, recapitulation and Christus Victor; the cross is efficacious, not merely an example.
Worked example
A candidate asks whether God died on the cross. Reasoning: the subject who died is the divine Person, but death belongs to his human nature. Divinity is impassible and did not cease. Because of the communicatio idiomatum, the Church may say the Son of God suffered and died in his human nature; she may not say the divine nature suffered. Verdict: the statement is true of the Person, false of the divine nature.
Traps
Docetism, adoptionism, Apollinarianism, Nestorianism, Eutychianism and monothelitism; saying Mary is mother only of Jesus' humanity; separating the cross from the resurrection; reducing salvation to forgiveness without divinization and restoration.
